The cooler and each fan link to separate profiles. The air duct is a test accessory, and the result belongs to the complete configuration above.

Farther from the center means a higher relative result within the same test environment. Only measured metrics with at least three comparable records are included; missing values are omitted, and acoustics stays out until enough formal dBA data exists.

S5M COMPONENT TEMPERATURES

Component temperatures

Averages from the final five minutes of AIDA64, with maxima shown separately. These values reveal overhanging airflow and in-case heat soak and are not folded into the CPU cooling rank.

Still warming at the endMaximum late-run sensor slope was 0.35°C/min. The direction of change is useful, but exact deltas remain provisional.
Test-condition noteThe heat-pipe ends of this cooler interfere with the test motherboard's VRM heatsink, so the VRM heatsink was removed for these runs. The VRM and nearby components therefore lack their normal passive cooling; the reported temperatures may be higher and are for observation only, not for direct comparison with tests that retained the VRM heatsink.
